Using the deep neural network to perform the vehicle lamp detection on the image block having the vehicle in the embodiments of the present disclosure facilitates rapid and accurate obtaining of the vehicle lamp detection result of the image block, thereby facilitating application of the vehicle lamp detection technique provided by the embodiments of the present disclosure to a real-time environment for intelligent driving such as automatic driving and assistant driving, so as to facilitate improvement of the decision accuracy and early warning accuracy of intelligent driving.

In an optional example, the sample image block including the image of the vehicle in the embodiments of the present disclosure may be an entire image to be processed and may also be a partial image including the image of the vehicle in the image to be processed. In addition, the image block including the image of the vehicle in the present disclosure may also be the image block obtained by processing the partial image including the image of the vehicle in the image to be processed.

In an optional example, the image to be processed in the embodiments of the present disclosure is a static image such as a picture or photo, or a video frame in a dynamic video, for example, a video frame in a video captured by a camera apparatus disposed in the vehicle. The vehicle in the image to be processed can be the vehicle located behind the vehicle where a camera apparatus is located captured by the camera apparatus (including right astern, side astern, etc.), may also be the vehicle in front of the vehicle where the camera apparatus is located captured by the camera apparatus (including right ahead, side ahead, etc.), and may also be the vehicle at the abeam direction of the vehicle where the camera apparatus is located captured by the camera apparatus. The present disclosure does not limit the specific position relation of the vehicle in the image to be processed with respect to the vehicle where the camera apparatus is located.

In an optional example, the image block is an image to be processed; or the image block is a partial image including an image of a vehicle in the image to be processed; or the image block is an image block obtained by processing the partial image including the image of the vehicle in the image to be processed.

According to one or more embodiments of the present disclosure, the vehicle included in the image block in the embodiments of the present disclosure may be a whole vehicle (the vehicle at the rightmost in FIG. 2) and may also be a partial vehicle caused due to reasons such as blocking (i.e., a partial vehicle, such as multiple vehicles at the left side in FIG. 2). A specific expressive form of the vehicle in the image to be processed is not limited in the present disclosure.

In an optional example, the obtaining the image block including the image of the vehicle includes:

performing vehicle detection on an image to be processed; and

segmenting the image to be processed according to the vehicle detection result, to obtain the image block including the image of the vehicle.

According to one or more embodiments of the present disclosure, in the embodiments of the present disclosure, vehicle detection can be performed on the image to be processed so as to obtain the vehicle detection result, thereby segmenting the image to be processed according to the vehicle detection result; the image block including the image of the vehicle can be obtained, so as to facilitate improving the accuracy of the vehicle lamp detection. Under the condition that the image to be processed includes multiple vehicles, in the present disclosure, multiple image blocks including the image of the vehicle can be obtained by segmenting the image to be processed. The vehicle detection result is vehicle external frame information, for example, coordinates of two vertexes located on a diagonal line of the vehicle external frame.

In an optional example, the performing the vehicle detection on the image to be processed includes:

performing vehicle detection on the image to be processed using a vehicle detection model, to obtain vehicle external frame information in the image to be processed.

In the embodiments of the present disclosure, the neural network is used to perform vehicle detection on the image to be processed, thereby obtaining the vehicle detection result according to information output by the neural network. For example, the embodiments of the present disclosure may use a vehicle detection model (the vehicle detection model may be the neural network for vehicle detection) etc. to perform vehicle detection processing on the image to be processed. In some optional examples, the vehicle detection model in the embodiments of the present disclosure may be a Region-based Convolutional Neural Network (R-CNN), Fast R-CNN, or Faster R-CNN. The present disclosure does not limit the specific implementing mode of performing vehicle detection processing on the image to be processed to obtain the image block including the image of the vehicle. The present disclosure does not limit the specific structure of the vehicle detection model (for example, the neural network for the vehicle detection), either. In the embodiments of the present disclosure, using the vehicle detection model to detect the vehicle from the image to be processed and segmenting from the image to be processed from the image block including the image of the vehicle facilitate reducing interferences of non-vehicle information in the image to be processed on the vehicle lamp detection, thereby facilitating reduction of the virtual detection rate of the vehicle lamp detection, so as to facilitate improvement of the accuracy of the vehicle lamp detection.

In an optional example, the size of the image block in the embodiments of the present disclosure is usually related to the requirement of a deep neural network for the size of an input image, for example, the size of the image block is 256×256. The deep neural network in the present disclosure is the deep neural network for vehicle lamp detection. To obtain the image block with a predetermined size, in the embodiments of the present disclosure, the image to be processed may first be scaled, and then the scaled image to be processed according to the predetermined size is segmented to obtain the image block including the image of the vehicle. In the present disclosure, the image to be processed can be scaled according to the vehicle detection result (for example, vehicle external frame information), so that the cut image block including the image of the vehicle has the predetermined size. Under the condition that the vehicle detection result for the image to be processed includes multiple pieces of vehicle external frame information, in the embodiments of the present disclosure, for the vehicle external frame information, correspondingly scaling the image to be processed enables at least one image block obtained based on the image to be processed to respectively have the predetermined size. In addition, in the embodiments of the present disclosure, segmenting can first be implemented and scaling can then be implemented. The embodiments of the present disclosure do not limit the size of the image block and the specific implementing mode of the scaling processing.

In an optional example, the performing the vehicle detection on the image to be processed further includes:

performing on multiple images to be processed having a timing sequence relation, to obtain corrected vehicle external frame information in the multiple images to be processed.

In the embodiments of the present disclosure, for the vehicle detection result output by the neural network (for example, the vehicle detection model), at least one of vehicle external frame leak detection or vehicle external frame smoothing processing can be executed (for example, before segmenting the image to be processed, executing the vehicle external frame leak detection and vehicle external frame smoothing processing), thereby facilitating the improvement of the accuracy of the vehicle detection result, so as to facilitate the improvement of the accuracy of the vehicle lamp detection result. In an optional example, under the condition that vehicle detection is performed on multiple video frames in a video, the multiple video frames usually have a timing sequence relation (for example, video frames continuously arranged in the video, and for example again, frame drawing for the video and multiple continuously drawn video frames formed based on a frame drawing result); in the embodiments of the present disclosure, the vehicle external frame leak detection and vehicle external frame smoothing processing are performed on the video frames (i.e., the image to be processed) having the timing sequence relation, so as to obtain the vehicle external frame information by means of leak detection of the vehicle detection model and perform position correction on the vehicle external frame information output by the vehicle detection model. For example, according to the vehicle external frames in the multiple video frames located before the n2-th video frame, the vehicle external frames in the n2-th video frame that are not detected are complemented; furthermore, for example, according to the vehicle external frames in the multiple video frames located before the n2-th video frame, the positions of the corresponding vehicle external frames in the n2-th video frame are corrected. In the embodiments of the present disclosure, according to multiple pieces of vehicle external frame information after the vehicle external frame leak detection and the vehicle external frame smoothing processing, the corresponding images to be processed are segmented respectively so as to obtain the multiple image blocks including the image of the vehicle having the timing sequence relation.

In an optional example, the performing the vehicle external frame leak detection and/or the smoothing processing on the multiple images to be processed having the timing sequence relation includes:

obtaining a vehicle identifier corresponding to at least one vehicle external frame according to the multiple images to be processed having the timing sequence relation and the vehicle external frame information thereof; and

performing the vehicle external frame leak detection and/or the vehicle external frame smoothing processing on at least one of the multiple images to be processed according to the vehicle identifier corresponding to the at least one vehicle external frame.

In the embodiments of the present disclosure, the image blocks in the multiple images to be processed having the timing sequence relation (i.e., the vehicle external frame information) can be first obtained; then the vehicle external frame leak detection and the vehicle external frame smoothing processing are then performed on the multiple images to be processed having the timing sequence relation and the vehicle external frame information.

In an optional example, in the embodiments of the present disclosure, an optional example of obtaining the image block in the multiple images to be processed having the timing sequence relation is: respectively providing the multiple images to be processed having the timing sequence relation and the vehicle external frame information in the at least one of the multiple images to be processed to a vehicle tracking model (the vehicle tracking model may be an article tracking model of the vehicle for the target object); in the embodiments of the present disclosure, the vehicle identifier corresponding to the at least one vehicle external frame is obtained according to information output by the vehicle tracking model. Hence, in the embodiments of the present disclosure, a respective association relation between at least one vehicle and a corresponding image to be processed is successfully established. Since the image block in the embodiments of the present disclosure is generated by segmenting the image to be processed based on the vehicle external frame information, the vehicle identification corresponding to the vehicle external frame is also be referred to as an image block identifier; the image block identifiers of the image blocks having the same vehicle are normally the same, while the image block identifiers of the image blocks having different vehicles are normally different. Hence, the vehicle lamp detection of the vehicle under the condition of multiple vehicles is facilitated.

In an optional example, the vehicle tracking model in the embodiments of the present disclosure may be a Convolutional Neural Network (CNN) or a Recurrent Neural Networks (RNN) based on adjacent front and back two video frame comparison.

In an optional example, the performing the vehicle external frame leak detection and/or the vehicle external frame smoothing processing on the at least one of the multiple images to be processed according to the vehicle identifier corresponding to the at least one vehicle external frame includes:

for a vehicle identifier, predicting a position of a vehicle external frame having the vehicle identifier in an m2-th image to be processed according to positions of vehicle external frames having the vehicle identifier in n2 images to be processed in front of the m2-th image to be processed; and performing vehicle external frame addition or vehicle external frame position correction processing on the m2-th image to be processed based on the predicted position of the vehicle external frame.

In the embodiments of the present disclosure, according to the multiple images to be processed having the timing sequence relation and the image block identifiers of the multiple images to be processed, the vehicle external frame leak detection and the vehicle external frame smoothing processing are executed; for example, the following formula (1) is used for executing the vehicle external frame leak detection and vehicle external frame smoothing processing for the current video frame: Δx=a ₁ t ² +b ₁ t+c ₁ Δy=a ₂ t ² b ₂ t+c ₂ Δw=a ₃ t ² b ₃ t+c ₃ Δh=a ₄ t ² +b ₄ t+c ₄  formula (1)

In the formula (1), a₁, a₂, a₃, a₄, b₁, b₂, b₃, b₄, c₁, c₂, c₃, and c₄ are all parameters for a linear equation (i.e., formula (1)); t represents a t-th moment before the current moment (for example, t=0, t=8, each moment corresponds to a video frame, i.e., each moment corresponds to an image to be processed); Δx represents a difference between a central point horizontal coordinate of the vehicle external frame in a preceding video frame and a central point horizontal coordinate of the vehicle external frame having the same vehicle identifier in the next video frame; Δy represents a difference between a central point vertical coordinate of the vehicle external frame in a preceding video frame and a central point vertical coordinate of the vehicle external frame having the same vehicle identifier in the next video frame; Δw represents a difference between a width of the vehicle external frame in a preceding video frame and a width of the vehicle external frame having the same vehicle identifier in the next video frame; Δh represents a difference between a height of the vehicle external frame in a preceding video frame and a height of the vehicle external frame having the same vehicle identifier in the next video frame.

According to one or more embodiments of the present disclosure, the performing vehicle external frame addition or vehicle external frame position correction processing on the m2-th image to be processed based on the predicted position of the vehicle external frame includes:

adding the vehicle external frame to the m2-th image to be processed according to the predicted position of the vehicle external frame under the condition that no vehicle external frame having the vehicle identifier exists in the m2-th image to be processed; or

performing weighted average processing on the predicted position of the vehicle external frame and the position of the vehicle external frame having the vehicle identifier in the m2-th image to be processed under the condition that the vehicle external frame having the vehicle identifier exists in the m2-th image to be processed.

In the embodiments of the present disclosure, the parameters a₁, a₂, a₃, a₄, b₁, b₂, b₃, b₄, c₁, c₂, c₃, and c₄ in the linear equation in formula (1) are calculated according to the vehicle external frame information having the same vehicle identifier in the preceding N (for example, N=8) video frames (i.e., the preceding N moments) of the current video frames (i.e., the current moment). Therefore, in the embodiments of the present disclosure, under the condition that the parameters of the formula (1) are known, Δx, Δy, Δw, and Δh corresponding to the current video frame are calculated using the formula (1); for a vehicle identifier, in the embodiments of the present disclosure, according to the position of the vehicle external frame having the vehicle identifier in the preceding video frame of the current video frame and the calculated Δx, Δy, Δw, and Δh corresponding to the current video frame, the position of the vehicle external frame having the vehicle identifier in the current video frame is predicted; if the current video frame does not have the vehicle external frame having the vehicle identifier, in the embodiments of the present disclosure, according to the predicted position of the vehicle external frame, the vehicle external frame is added to the current video frame, thereby implementing the vehicle external frame leak detection processing on the current video frame; if the current video frame has the vehicle external frame having the vehicle identifier, in the embodiments of the present disclosure, weighted averaging is executed according to the predicted position of the vehicle external frame and the position of the vehicle external frame having the vehicle identifier in the current video frame, thereby implementing the smoothing processing on the vehicle external frame having the vehicle identifier in the current video frame.

In addition, in the embodiments of the present disclosure, existing other leak detection processing and smoothing processing techniques are used for performing the vehicle external frame leak detection processing and the vehicle external frame smoothing processing on the multiple video frames. The embodiments of the present disclosure do not limit the specific implementing mode of performing vehicle external frame leak detection processing and the vehicle external frame smoothing processing on the image to be processed. The embodiments of the present disclosure do not limit the specific structures of the vehicle tracking model, either.

In an optional example, the deep neural network in the embodiments of the present disclosure may use the deep neural network based on region detection; for example, Region-based Convolutional Neural Network (R-CNN) or Faster R-CNN are used. The network structure of the deep neural network may be flexibly designed according to actual requirements for extracting the vehicle lamp detection results; the embodiments of the present disclosure do not limit the specific network structure of the deep neural network; for example, the deep neural network in the embodiments of the present disclosure may include, but not limited to, a convolutional layer, a nonlinear Relu layer, a pooling layer, and a full connection layer. The more the number of layers included by the deep neural network, the deeper the network. Furthermore, for instance, the network structure of the deep neural network of the embodiments of the present disclosure may adopt, but not limited to, network structures adopted by neural networks such as ALexNet, a Deep Residual Network (ResNet), or Visual Geometry Group Network (VGGnet).

According to one or more embodiments of the present disclosure, in the embodiments of the present disclosure, the deep neural network is obtained by training using a sample image block having vehicle lamp annotation information, so that the trained deep neural network has the capability of accurately detecting a vehicle lamp state. To improve the training efficiency of the neural network, the vehicle lamp annotation information of the sample image block includes: at least one or more of vehicle lamp external frame information annotation information, vehicle lamp on-and-off state annotation information, and vehicle lamp orientation annotation information. Reference may be made to the descriptions for FIG. 3 for the process of training the deep neural network. Descriptions are not made herein repeatedly.

In an optional example, in the embodiments of the present disclosure, the vehicle lamp detection result output by the deep neural network includes, but not limited to, at least one of the vehicle lamp external frame information, the vehicle lamp on-and-off state, or the vehicle lamp orientation. For example, the deep neural network outputs the vehicle lamp external frame information, the vehicle lamp on-and-off state, and the vehicle lamp orientation. The vehicle lamp external frame information normally refers to information capable of showing the position of the vehicle lamp external frame in the image block (for example, the coordinates of the two vertexes of the diagonal line of the vehicle lamp external frame on the image block), therefore, in the embodiments of the present disclosure, the position of the vehicle lamp in the image to be processed is determined according to the position of the vehicle lamp external frame in the image block (for example, the coordinates of the two vertexes of the diagonal line of the vehicle lamp external frame on the image to be processed). Certainly, the vehicle lamp external frame information output by the deep neural network can also directly be information of the position of the vehicle lamp external frame in the image to be processed (for example, the coordinates of the two vertexes of the diagonal line of the vehicle lamp external frame on the image block to be processed). The vehicle lamp on-and-off state normally shows whether the vehicle lamp is in an on state or an off state. The vehicle lamp orientation normally is used for indicating the orientation of the vehicle lamp in the vehicle, for example, the vehicle lamp orientation may be: the left front vehicle lamp, the right left vehicle lamp, the left rear vehicle lamp, or the right rear vehicle lamp.

In an optional example, before the determining the vehicle lamp indication information according to the vehicle lamp detection results of the multiple image blocks having the timing sequence relation, the method further includes: performing vehicle lamp external frame leak detection and/or vehicle lamp external frame smoothing processing on the multiple image blocks having the timing sequence relation according to the vehicle lamp detection results, to obtain corrected vehicle lamp external frame information in the multiple image blocks.

In the embodiments of the present disclosure, at least one of the vehicle lamp external frame leak detection or vehicle lamp external frame smoothing processing is executed for the vehicle lamp detection result output by the deep neural network, so as to facilitate the improvement of the accuracy of the vehicle lamp detection result. In an optional example, under the condition that vehicle detection is performed on multiple image blocks, the multiple image blocks usually have a timing sequence relation (for example, at least one image block in the multiple video frames continuously arranged in the video, and for example again, frame drawing for the video and at least one image block in the multiple continuously drawn video frames formed based on a frame drawing result); in the embodiments of the present disclosure, the vehicle lamp external frame leak detection and vehicle lamp external frame smoothing processing are performed on the multiple image blocks having the timing sequence relation, so as to obtain the vehicle lamp external frame information by means of leak detection of the deep neural network and perform position correction on the vehicle lamp external frame information output by the deep neural network. For example, according to the vehicle lamp external frames in the multiple image blocks located before the n1-th image block, the vehicle lamp external frames in the n1-th image block that are not detected are complemented; furthermore, for example, according to the vehicle lamp external frames in the multiple image blocks located before the n1-th image block, the positions of the corresponding vehicle lamp external frames in the n1-th image block are corrected. In the embodiments of the present disclosure, vehicle lamp indication information analysis is executed according to the at least one piece of vehicle lamp external frame information after the vehicle lamp external frame leak detection and vehicle lamp external frame smoothing processing and other information such as the vehicle lamp on-and-off states.

In an optional example, the performing the vehicle lamp external frame leak detection and/or the vehicle lamp external frame smoothing processing on the multiple image blocks having the timing sequence relation according to the vehicle lamp detection results includes:

obtaining a vehicle lamp identifier corresponding to at least one vehicle lamp external frame according to the multiple image blocks having the timing sequence relation and the vehicle lamp external frame information in the multiple image blocks; and performing the vehicle lamp external frame leak detection and/or the vehicle lamp external frame smoothing processing on at least one of the multiple image blocks according to the vehicle lamp identifier corresponding to the at least one vehicle lamp external frame.

According to one or more embodiments of the present disclosure, in the embodiments of the present disclosure, the vehicle lamp external frame information (the coordinates of two vertexes located on a diagonal line of the vehicle lamp external frame) in the multiple image blocks having the timing sequence relation is first obtained; then the vehicle lamp external frame leak detection processing and the vehicle lamp external frame smoothing processing are executed for the multiple image blocks having the timing sequence relation and the at least one piece of the vehicle lamp external frame information.

In an optional example, in the embodiments of the present disclosure, respectively providing the multiple image blocks having the timing sequence relation and the vehicle lamp external frame information to a vehicle lamp tracking model (the vehicle lamp tracking model may be an article tracking model of the vehicle lamp for the target object); in the embodiments of the present disclosure, the vehicle identifier corresponding to the at least one vehicle lamp external frame is obtained according to information output by the vehicle lamp tracking model. Hence, in the embodiments of the present disclosure, an association relation between the vehicle lamp and the vehicle is successfully established. Different vehicle lamp external frames having the same vehicle lamp identifier generally correspond to the same vehicle lamp of the same vehicle.

In an optional example, performing the vehicle lamp external frame leak detection and/or the vehicle lamp external frame smoothing processing on at least one of the multiple image blocks according to the vehicle lamp identifier corresponding to the at least one vehicle lamp external frame includes:

for a vehicle lamp identifier, predicting a position of a vehicle lamp external frame having the vehicle lamp identifier in an m1-th image block according to positions of vehicle lamp external frames having the vehicle lamp identifier in n1 image blocks in front of the m1-th image block; and

performing vehicle lamp external frame addition or vehicle lamp external frame position correction processing on the m1-th image block based on the predicted position of the vehicle lamp external frame.

Therefore, in the embodiments of the present disclosure, under the condition that the parameters of the formula (1) are known, Δx, Δy, Δw, and Δh of the current image block are calculated using the formula (1); for a vehicle lamp identifier, in the embodiments of the present disclosure, according to the position of the vehicle lamp external frame having the vehicle lamp identifier in the preceding image block of the current image block and the calculated Δx, Δy, Δw, and Δh corresponding to the current image block, the position of the vehicle lamp external frame having the vehicle lamp identifier in the current image block is predicted; if the current image block does not have the vehicle lamp external frame having the vehicle lamp identifier, in the embodiments of the present disclosure, according to the predicted position of the vehicle lamp external frame, the vehicle lamp external frame is added to the current image block, thereby implementing the vehicle lamp external frame leak detection processing on the current image block; if the current image block has the vehicle lamp external frame having the vehicle lamp identifier, in the embodiments of the present disclosure, weighted averaging is executed according to the predicted position of the vehicle lamp external frame and the position of the vehicle lamp external frame having the vehicle lamp identifier in the current image block, thereby implementing the smoothing processing on the vehicle lamp external frame having the vehicle lamp identifier in the current image block.

In addition, in the embodiments of the present disclosure, existing other leak detection processing and smoothing processing techniques are used for performing the vehicle lamp external frame leak detection processing and the vehicle lamp external frame smoothing processing on at least one image block in the at least one video frame. The embodiments of the present disclosure do not limit the specific implementing mode of performing vehicle lamp external frame leak detection processing and the vehicle lamp external frame smoothing processing on the image block in the image to be processed.

The trend of an entire vehicle is determined by combining the states of the two vehicle lamps (for example, two rear vehicle lamps) of the same vehicle, so that accurate, rapid, and intuitive information are provided to a vehicle environment sensing system in the intelligent drive system, thereby facilitating help of the intelligent driving system for decision, so as to facilitate more secured and faster driving of the vehicle.

$\begin{matrix} {c_{i} = {\sum\limits_{n = i}^{i + 14}s_{n}}} & {{formula}\mspace{20mu}(2)} \\ {A_{i} = \left\{ \begin{matrix} {0,{C_{i} \leq 8}} \\ {1,{8 < C_{i} \leq 13}} \\ {2,{C_{i} > 13}} \end{matrix} \right.} & {{formula}\mspace{14mu}(3)} \\ {D_{m} = {{count}\mspace{11mu}\left( {A_{i} = m} \right)}} & {{formula}\mspace{14mu}(4)} \\ {S_{t} = \left\{ \begin{matrix} {2,{D_{1} = 0},{D_{2} \neq 0}} \\ {1,{D_{2} = 0},{D_{1} \neq 0}} \\ {0,{other}} \end{matrix} \right.} & {{formula}\mspace{14mu}(5)} \end{matrix}$

In the formula (2), i represents an i-th phase; a phase generally includes multiple moments; s_(n) represents the on-and-off state of the vehicle lamp at an n-th moment; a value of s_(n) is 0, which represents that the vehicle lamp is in an off state at the n-the moment; a value of s_(n) is 1, which represents that the vehicle lamp is in an on state at the n-the moment; C_(i) represents the times for the vehicle lamp to be in an on state in the i-th phase.

It should be specially explained that the formulas (2)-(5) are only optional collecting statistics about modes; in the embodiments of the present disclosure, other collecting statistics about modes may be used for determining the vehicle lamp indication information, and the collecting statistics about modes may be flexibly designed according to actual requirements. The embodiments of the present disclosure do not limit the specific collecting statistics about mode of the vehicle lamp indication information.

FIG. 3 is a flowchart of a method for training a neural network provided by the embodiments of the present disclosure. The method may be performed by any electronic device, such as a terminal device, a server, a mobile device, and a vehicle-mounted device. As shown in FIG. 3, the method of the embodiments includes: steps S300, S310, and S320. Each step in FIG. 3 is illuminated in detail as follows.

S300, a sample image block including an image of a vehicle is obtained.

In an optional example, step S300 is performed by a processor by invoking a corresponding instruction stored in a memory, or is performed by a sample image block obtaining module 800 run by the processor.

S310, vehicle lamp detection is performed on the sample image block by means of a deep neural network to be trained, to obtain a vehicle lamp detection result.

In an optional example, the step S310 is performed by a processor by invoking a corresponding instruction stored in a memory, or is performed by a second vehicle lamp detection module 810 run by the processor.

S320, a difference between the vehicle lamp detection result and the vehicle lamp annotation information of the sample image block is used as guidance information to perform supervised learning on the deep neural network to be trained. In an optional example, step S320 may be performed by a processor by invoking a corresponding instruction stored in a memory, and may also be performed by a supervision module 820 run by the processor.

In an optional example, the sample image block including the image of the vehicle in the embodiments of the present disclosure may be an entire image sample and may also be a partial image including the image of the vehicle in the image sample. In addition, the sample image block including the image of the vehicle in the embodiments of the present disclosure may also be the sample image block obtained by processing the partial image including the image of the vehicle in the image sample.

In an optional example, the image sample is obtained from a training data set, and the sample image block including the image of the vehicle in the image sample is obtained. The training data set in the embodiments of the present disclosure includes multiple image samples for training the deep neural network. Under normal conditions, each image sample is provided with the vehicle lamp annotation information; the vehicle lamp annotation information includes, but not limited to, at least one of the vehicle lamp external frame information annotation information, the vehicle lamp on-and-off state annotation information, or the vehicle lamp orientation annotation information. In the embodiments of the present disclosure, one or more image samples may be read from the training data set at one time according to a random reading mode or an image sample arrangement order sequence reading mode.

In an optional example, in the embodiments of the present disclosure, multiple mode can be adopted to obtain the sample image block including the image of the vehicle, for example, in the embodiments of the present disclosure, the image block including the image of the vehicle in the image sample is obtained by means of the neural network. In an optional example, in the embodiments of the present disclosure, the vehicle detection is performed on the image sample, so as to obtain the vehicle detection result, thereby segmenting the image sample according to the vehicle detection result, so that the sample image block including the image of the vehicle can be obtained. Under the condition that the image sample includes multiple vehicles, in the embodiments of the present disclosure, multiple sample image blocks including the image of the vehicle can be obtained by means of segmenting the image sample. The vehicle detection result is vehicle external frame information, for example, coordinates of two vertexes located on a diagonal line of the vehicle external frame.

In an optional example, in the embodiments of the present disclosure, the vehicle detection model (also referred to as the target object being the article detection mode of the vehicle) and the like are used to perform vehicle detection on the read image sample. The embodiments of the present disclosure do not limit the specific implementing mode of performing vehicle detection on the image sample to obtain the sample image block including the image of the vehicle.

In an optional example, the size of the sample image block in the embodiments of the present disclosure is usually related to the requirement of a deep neural network for the size of an input image, for example, the size of the sample image block is 256×256. To obtain the sample image block having the predetermined size, in the embodiments of the present disclosure, after vehicle detection is executed, the image sample is scaled according to the vehicle detection result, and then according to the predetermined size and the vehicle external frame information (for example, a central position of the vehicle external frame), the sample image block having the vehicle is obtained by segmenting the scaled image sample. Under the condition that the vehicle detection result includes multiple pieces of the vehicle external frame information, in the embodiments of the present disclosure, for at least one piece of the vehicle external frame information, the image sample is scaled by corresponding multiples, separately, so that the obtained at least sample image block separately has the predetermined size. The embodiments of the present disclosure do not limit the size of the sample image block and the specific implementing mode of the scaling processing.

In an optional example, in the embodiments of the present disclosure, the deep neural network to be trained would perform vehicle detection on the input at least one sample image block, and output the vehicle lamp detection result, for example, outputting at least one of the vehicle lamp external frame information, the vehicle lamp on-and-off state, or the vehicle lamp orientation. Under normal conditions, the deep neural network to be trained outputs the vehicle lamp external frame information, the vehicle lamp on-and-off state, and the vehicle lamp orientation for the at least one sample image block. The vehicle lamp external frame information normally refers to information capable of showing the position of the vehicle lamp external frame in the sample image block (for example, the coordinates of the two vertexes of the diagonal line of the vehicle lamp external frame on the sample image block), therefore, in the embodiments of the present disclosure, the position of the vehicle lamp in the image sample is determined according to the position of the vehicle lamp external frame in the image block (for example, the coordinates of the two vertexes of the diagonal line of the vehicle lamp external frame on the image sample).

Certainly, the vehicle lamp external frame information output by the deep neural network to be trained is also directly the information of the position of the vehicle lamp external frame in the image sample. The vehicle lamp on-and-off state normally shows whether the vehicle lamp is in an on state or an off state. The vehicle lamp orientation normally is used for indicating the orientation of the vehicle lamp in the vehicle, for example, the vehicle lamp orientation may be: the left front vehicle lamp, the right left vehicle lamp, the left rear vehicle lamp, or the right rear vehicle lamp.

In an optional example, in the embodiments of the present disclosure, the difference between the vehicle lamp detection result of the at least one sample image block output by the deep neural network to be trained and the vehicle lamp annotation information of the corresponding sample image block is used as the guidance information; reducing the difference is the goal; a corresponding loss function is used for supervised learning of the deep neural network to be trained.

In an optional example, when the training for the deep neural network to be trained meets a predetermined iteration condition, this training process ends. The predetermined iteration condition in the embodiments of the present disclosure includes that the difference between the vehicle lamp detection result output by the deep neural network to be trained and the vehicle lamp annotation information of the image sample meets a predetermined difference requirement. When the difference meets the predetermined difference requirement, this training for the deep neural network to be trained successfully ends. The predetermined iteration condition in the present disclosure also includes: training the deep neural network to be trained, the number of used image samples meeting a predetermined number requirement, etc. Under the condition that the number of used image samples meets the predetermined number requirement but the difference does not meet the predetermined difference condition, this training for the deep neural network to be trained does not succeed. The successfully trained deep neural network is used for performing the vehicle lamp detection processing on the image block including the image of the vehicle.
